Application filed July 24,

To all whom t may concern:

Be it known that LFnrrz Meran, a citizen ,of the German Empire, residing' at Ulm-onthe-Danube, Republic of Germany, have invented certain new and useful llrnprovemeut in Motor-Ears, of which the following is a specification, reference being had there in to the mcompanying drawing.

My invention relates to motor vehicles and more particularly motor trucks, and

the object ot my invention is to so construct the vehicle that the front-part containing the driving mechanism can be madel short and compact, at the same time permitting the frame of the car to be low,

ln the accompanyingdrawings illustrating my invention, Fig. 1 is a cross-section through the iront part of a truck embodying my invention; Fig. 2 is a top View of the same with the drivers seat removed; Fig. 3 is a View similar to .Figure 1, showing a modication; Fig. 4 is a plan of the iront part with the drivers seat omitted. (Figs. l-t are diagrammatic views.) Fig. 5 is a longitudinal section through a truck built according to my invention; Fig. 6 is a plan view.

a, designates the' inotor, b, the set ot speed-change gears and c, the differential gea-1f, these three parts being constructed to form one integral whole. From the diderential gear c, the two articulated shafts d, d which pass above the frame c, e are driving the front wheels. ylhe motor an, without the medium of the usual friction coupling, drives by the aid of the bevel-gear-wheel 7L, the lower gear-shaft i which accordingly is continuously rotated by the motor.

According to Figs. 1 and 2, l dispose the gear-shaft fm., and the diderential gear c vertically above the lower gear-shaft therebyl considerably reducing the length ot .the gearing, aswell as preventin the motor from extending. too far beyon the front axle?. the modication according to Fig. 3, the -shaft of the diderentialgear c is disposed in a lower horizontal position. By thus lowering the diferential gear c ll am able to considerably raise the position ot the motor without thereby increasing theI height TR CAB.

ment the same advantages are obtained as with an electrically propelled vehicle, in-

which the motor is located below the trame coupled directly with the front wheels. Thus, also the rear portion of the truck can be constructed and shaped in any desired manner, as the drivin mechanism is located entirely in front lghis is of the greatest importance for the construction ot' trucks for special industrial uses. Moreover, the whole construction is considerably reduced' in weight and is more easy to inspect, as there are no parts of the machinery and transmission concealed below the body of thev truck. The seat p for thedriver being lo# cated directly above the dierential-gear, the length di the truck is thereby considerably reduced. ln Figs. 5, and 6J a motor truck built in accordance with my invention is shown in detail, the referenceletters appearing in said figures indicating the same parts as the parts indicated by the same reference letters in Figs. 1-4, m1, m2 and ma, showing the speed-change gears. n designates the front axle.

No claim is made to any novelty in the specic form of the change speed gearing disclosed in Figs. 5 and 6, beyond what is claimed in the claim attached' to this specification.

l claim as my invention:
